transmission thermostat

[Marky Dissod]

do we have to do, trans thermostat mod?
I see silverado folks talking about it .

No, if you intend to sell it before 2029.
If, however, you want to keep it well beyond that, certain mods are famous for improving drivability, longevity, and durability beyond OE.
Yes, deleting Cylinder deactivation (instead of just turning it off) is one of them.
Yes, tuning is another.
Yes, depending on your use case, better axle gears may also be in the mix.

With the Transgo or Shift Technologies kits, is one better than the other? I know to avoid the clones on certain online sites.
